IMPROVED PAINT-BRUSH.

TO ALL WHOM II MAY CONCERN:

-Be it known that I, JOSEPH, W. MOORE, of Oambridgeport, in the county of Middlesex, and State of Massachusetts, have invented an Improvement in Brushes, of which the following is a full, clear, and'exact description, reference being had tothe accompanying drawings, making part ofth'is specification, in which-' Figure 1 is an elevation of my improved brush. Figure 2 is a central longitudinal section through the same.

This invention consists in a socket or holder, the upper portion of which is made removable, sc as to allow the bristles to bev inserted at'the top, in combination with a wedge, held in place by the lower end of the handle, which is provided with a screw-thread; and passesthrough the removabletop o f the holder,'by which arrange` ment the bristles are held firmly in place, and all liability is avoided of 'the brush falling to pieces in consequence of the shrinkage of the-handle-an event of frequent'occurrence with brushes as ordinarily constructed.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner-in which I have carried it out. v

In the drawings, A is a metallic socket or holder, which is made of a tapering form, and is provided with a removable screwftop, a, so as to allow the bristles to he inserted at the upper end of the. holder.' is a conical wedge, composed of wood, or other suitable material, which is driven in between the bristles at the centre, and forces them tightly against the inside ofthe socket which is provided at its lower end with a shoulder or projection,3, extending entirely aroundl it, which assists in holding the bristles in place. -The wedge B is elongated, and extends up above the top'of thebristle's into the-hollow metallic end of the handle C, which is provided on the outside with a screw-thread, b, and works in the removable top a, its lower extremity resting,

when in place, on a. shoulder, c, formed'on thewedge B, thus serving to ho'ld .it down firmly-in place and prevent any liability of its being displaced. The upper portion, 4, of the wedge ai'i'ords a hold, so that it may be withdrawn in case (after the brush is worn out) it should be desired to remove the bristles and replace them with others, which could not easily be done if the wedge were cut off atv the top of the bristles; and by thus constructing the brush, so that the bristles'when worn out maybe easily removedand replaced, a great saving may be effected, as the metallic holder and the lower. portion of the handle possess great strength, and will last for a great length oi` time. 'l i I am aware that brushes have been made with metallic sockets .to screw together, as in the case of I. Cross, patented VJuly 5, 1853, and which also have the tapering wedge for holding the bristles, but the mode of inserting my screw-top a has amaterial advantage, as it closes the seam tight, and thus prevents the possibility ot' paint entering it, while th'e seam'in Crosss patent is open and exposed to the paint. I am also aware that metal sockets have been formed toreceive the handle, but my improved mode of introducing the handle by means'of a screw into the movable top a, has the great advantage of tightening the wedge by merely turning vthe handle of the brush.

C'Zaz'm.

What I'clailn as my invention, and desire to secure by Letters Patent, is- The removable screw-top a, and the handle C, with a screw-thread, b, in combination with wedge B, with its shoulder c, al-l constructed and operating substantially as and for the purposedescribed.
